Cesium sorption by clinoptilolite-rich tuffs in batch and fixed-bed systems
The sorption of cesium by two different clinoptilolite-rich tuffs from Mexico considering both batch and continuous flow systems was investigated. The kinetic and thermodynamic parameters as well as the sorption capacities of the zeolitic materials at different temperatures were evaluated. It was fo...

| description | The sorption of cesium by two different clinoptilolite-rich tuffs from Mexico considering both batch and continuous flow systems was investigated. The kinetic and thermodynamic parameters as well as the sorption capacities of the zeolitic materials at different temperatures were evaluated. It was found that the second order model describes the cesium sorption kinetics and the Langmuir–Freundlich model describe the isotherms, in all cases. According with the thermodynamic parameters the cesium sorption mechanism is ion exchange and endothermic in nature. The mineral and chemical composition of the clinoptilolite-rich tuff influences on the cesium sorption properties. |
